Description
TACKWHITE SB4 AF is a waterborne P.S.A., based on synthetic carboxylated SBR latices and stabilized rosin esters.
TACKWHITE SB4 AF has very good stability and ageing resistance.
The coated dry product is transparent, but slightly yellowish, being based on SBR latices.
Application
Permanent paper labels, wovens, paper and paperboard, with high adhesive power.
